' To all it may concern 5 Be it known that I, Crcnno R. Bnnvns, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Photographers Portable Lights, of which the followmg 1s a s ecification, reference being had therein to t e accompanying drawing.

.The invention relates to a photographers light and has for its object to provide a device of this character wherein an ultra brllliance of pure white light is obtained, which light is properly diffused and the device so constructed that it may be collapsed into the form of a suit case, thereby allowing the same to be easily transported from place to place.

A further object is to provide a photog-- 'raphers light, the container of which 15 rectangular shaped and formed in two sec tions, said sections being hingedly connected together and wider at their diagonally disposed sides thereby providing W1 e bases on which lights are disposed and at the same time allowing one of the wide bases to be secured to a tripod in such a manner that its section is equally balanced thereon when the other section is hinged downwardly to a. position where its outer surface Will engage the upper end of the tr1pod for bracing the same against swinging action. I l

A further object is to so dispose the lights in each section that when the sections are in closed position, lights will be disposed the upper end of the upper section, said connection of the screen to the ivoted arms being by means of a telescoping rod and hook, said screen and rods being adapted to be disposed within the casing when the same is in folded position. a

A further object is to form the upper ends of the sections, when said sections are in open position narrower than their lower ends, thereby allowing the escape of heat.

Also to provide a heat insulated bright aluminum lining in the sections, which linings act as reflectors for reflecting the light and the heat insulation thereof preventing fire and deterioration of the material from which the sections are formed.

With the above and other objects in View the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes a in the precise embodiment of the invention may be-made within the scope of what is claimed without departing from the spirit of the invention.

In'the drawings Figure 1 is a perspective view of the light casing showing the same in closed position for transporting from place to piece,

Fig. 2 is an end elevation of the casing showing the sections thereof closed, 3 is a front View of the light showing the casing sections in open position and supported on a tripod, the screen being eliminated tobetter show the structure.

Fig. 4 is a vertical transverse sectional View taken on line Jr-4*; of Fig. 3, and showing the difiusing screen in position.

Fig. 5 is a top plan View of the device showing the same in open position.

Fig. 6 is a perspective view of the diifusing screen and its telescoping supporting itclerring to the drawings, the numerals l and 2 designate rectangular shaped sections which the casing, said s being hingedly connected. to-

lihe lower of the 1 is wider than the lower side 5 of the section 2, while the upper side 6 of the section 2 is wider than the upper side 7 of the section 1. By constructing the side at widerthan the side 5, it will be seen that when the side 4: is disposed on. a tripod 8 as shown in Figure t and secured thereto as at 9, that the section 1 will have its weight equally balanced on the tripod and that the section 2 when folded downwardly will engage the upper end of the tripod 8, thereby bringing the weight of the section 2 adjacent the tripod so that the tripod will be stable, and the possibilities of tilting over of the tripod will be reduced to a minimum. It will also be seen that by forming the sides 4 and 6 wider than their opposite sides that light supporting bases 10 will be termed on which light sockets may be disposed, thereby not only forming wide bases for supporting the lights 12 and 13, but also forming plenty of room for wiring and the llke. By forming the sides 5 and 7 narrower than the sides 4 and 6, it will be seen that the accumulation of heat within the upper ends of the chambers 14 of the sections 1 and 2 will be reduced to a minimum and the heat allowed to rise, thereby reducing the possibility of fire to a minimum. Sections 1 and 2 are lined with aluminum, which is bright and reflects the light from the sections through the difl'using screen 16. Interposed between the aluminum linings 15 and the walls of the sections 1 and 2 are asbestos layers, which layers prevent the radiation of the heat from the aluminum to the walls of the sections, thereby preventing said Walls from becoming hot incident to the intense heat radiated by the lights 12 and 13.

The upper side 6 of the. section 2 is provided with a handle 20 adapted to be grasped by the operator when transporting the dc- -v1ce from place to place said side 6 also being provided with a lock 21, by means of which look the sections may be locked together during transporting or when the device is not in use.

Electric conductor wires 22 and 23 are provided whereby electric current may be conducted to the lights 12 and 13, the lights 13 preferabl being in circuit with the lights 12. he wires 23 are connected to a socket 2 1, to which socket are detachably connected by means'of a plug 25,- conductor wires 26 which lead to any suitable source of current supply, thereby being a switch 27 for controlling said current. When the sections are in closed position as shown in Fig. 2 the wires 28 and socket24 are disposed within the section 2 after the plug 25 has been detached. It will be seen that the case when in folded position as shown in Fig. 1 is free from outside connections and that all of its operating parts are entirely concealed within the case.

The diffusing screen 16 is preferably formed of georgette silk and has been found to give an ultra brilliance and a pure whiteness of light. However it is, to be understood that the material may be varied if so desired. The diffusing screen at its up er and lower ends is provided with preferably wire rings 28, which rings have passing through them extensible rods 29 and 30. The sections of the rod 29 are provided with projections 31, which pro'ections are received by apertures 32 in rackets 33 carried by the casing section 2. When the sections of the extensible rod 29 are forced outwardly, it will be seen that the brackets 33 will hold the screen 16 at its lower end. The screen 16 extends upwardly and has upper rings 28 disposed on the extensible rod 30, the ends of the sections of which are provided with hooks 34, which hooks are adapted to be received by any of the apertures 35 of the spring supporting arms 36, which arms maintain the screen 16 in a substantially stretched condition in front of the li hts 12 and 13 so that the li ht rays will e deflected through the iflusing screen. The spring arms 36 are pivotally secured as at 37 in the upper end of the chamber 14 of the section 1 of the casing. When the arms are not in use they are folded into the chamber 14 as clearly shown in Fig. 3, thereby allowing the casing sections 1 and 2 to be closed to the position shown in Fig. 1. It will be noted that the diflusing screen 16 extends upwardly and outwardly thereb reducing the possibility of collection 0 heat to a minimum, and it will also be noted that by adjusting the hooks 34 in any of the apertures 35 of the'spring arm 36 that the intenseness of whiteness and the reflection of light through the screen may bevaried.

From the above it will be seen that a photographers portable light is provided which is compact, the parts reduced to a minimum and the sections 1 and 2 of the casing so proportioned that the same ma be easily and quickly disposed on a tripo and when so disposed the center of gravity of the parts so balanced on the axis of the tripod, that the tripod will be stable and the possibility of tilting reduced to a minimum. It Wlll also be seen that by using different heights of light 12 and 13 that the reflected light will beQscattered and uniform as it passes through the diffusing screen 16.

The invention having been set forth what is claimed as new and useful is 1. A light of the character described comprising superimposed hin edly connected casings, the upper ends of t e casings being narrower than their lower ends, means carried by the lower ends of the upper casing for the reception of a support, lights disposed in the casings and supported on their wide sides and a diffusing screen disposed in front of the lights;
